2.用法
(1)表示动作发生在过去某个不确定的时间，但对现在留下了某种影响和结果。常被just、already、yet 等副词修饰。如：
-Have you had lunch yet? -Yes,I have. I've just had it.
你(已经)吃午饭了吗? 我刚刚吃过。(现在我不饿了)
(2)表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止，可能仍然在进行。常带有for和since等表示一段时间的状语。 如：He has taught here since 1981
他自1981年就在这儿教书。(可能还要继续教)
I have't seen her for four years.
我有四年没见到她了。
